alt Hacker NewsLife is full of such gambles and it's inevitable.
Anyone who drives risks their life more than they risk having a special needs child at reasonably non-late age.
We just brush off most such gambles because:
1. People have a terrible intuition for probabilities.
2. If it were better, they would go insane.
I agree. I'm saying that "just have kids younger" isn't a good solution to the risks of developmental defects, because it's usually merely a trade of that risk for a different one.
